Transformers and a Few of Their Common types
According to Wikipedia, “transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electric power applications.
A varying current in the transformer's primary winding creates a varying magnetic flux in the transformer core and a varying field impinging on the transformer's secondary winding. This varying magnetic field at the secondary winding induces a varying electromotive force (EMF) or voltage in the secondary winding due to electromagnetic induction. Making use of Faraday's Law (discovered in 1831) in conjunction with high magnetic permeability core properties, transformers can be designed to efficiently change AC voltages from one voltage level to another within power networks.”
Transformers play a vital role in transferring energy between circuits. They help in either increasing or lowering voltage levels to decrease line loses in transmission.In modern system, transformers are usually used to boost voltage levels.
Single phase transformers are more common as compared to the three phase transformers especially in the urban areas. This is mainly because the distribution network cost of single phase transformers is lower. Therefore, you should look for renowned single phase transformer manufacturers for your project.
A few common types of transformers
- Auto transformers
These transformers share a common winding which makes it different from the traditional ones. For winding there exists an end terminal on each end of the transformer core and a third terminal is also formed for second winding.
- Polyphase Transformers
These types of transformers are associated with three phase electric power. Wondering what it is? It is a common method by which large amount of high voltage power is transmitted. In this phase there are three different wires that carry currents of the same frequency but reach their peak at different times.
- Leakage Transformers
These transformers come with a loose binding between the primary and secondary winding. This loose binding leads to inductance leakage in large amount and it helps in preventing overload. These transformers are useful for both low and high voltage applications.
Thus, you must have got an idea about transformers and their common types. There are many other types as well. Since single phase transformers are mostly used for both residential and commercial applications, you should look for some good single phase transformer manufacturers.
